ACT-America: Gridded Ensembles of Surface Biogenic Carbon Fluxes, 2003-2018
This dataset from the Atmospheric Carbon and Transport - America project provides gridded, model-derived gross primary productivity (GPP), ecosystem respiration (RECO), and net ecosystem exchange (NEE) of CO2 biogenic fluxes and their uncertainties at monthly and 3-hourly time scales over 2003-2018 on a 463-m resolution grid for the conterminous United States (CONUS) and also on a 5-km resolution grid for North America. The biogeochemical model is from the Carnegie Ames Stanford Approach (CASA).
The ACT-America, or Atmospheric Carbon and Transport - America, project is a NASA Earth Venture Suborbital-2 mission to study the transport and fluxes of atmospheric carbon dioxide and methane across three regions in the eastern United States. Each flight campaign measured transport of greenhouse gases by continental-scale weather systems. Ground-based measurements of greenhouse gases were also collected. Project goals included better estimates of the greenhouse gas sources and sinks which are required for climate management and for prediction of future climate.
